From the description: "Computer magazine's multimedia editor Charles Severance interviews Bob Metcalfe about the creation of the first Ethernet local area network 40 years ago at Xerox Palo Alto Research Center." We still use ethernet today, and Metcalfe, of course, is the namesake for "Metcalfe's Law", which states that"the value of a telecommunications network is proportional to the square of the number of connected users of the system" (per Wikipedia). More on Metcalfe's Law.
